液态铝液面测量
为了得到均匀无氧化铝铸件，需要控制在开放模具内的液态铝厚度不超过1mm。恒定的液面是通过控制熔炉倾斜角度进行控制的。而液态铝的液面是通过悬挂于液面上方的电涡流传感器（须空气冷却）进行测量的。德国米铱公司提供的电涡流传感器超强的温度稳定性以及高工作温度，使其成为这个测量任务的最佳选择。

Liquid Aluminium Level Measurement

To obtain a homogeneous oxide-free aluminium cast, the aluminium level in the open mould must be kept constant to within 1 mm or better. A constant level is achieved by controlled tilting of the furnace. The current level is measured and monitored from above with air-cooled eddy current sensors. A temperature-stable output signal and the high operating temperature of the eddy current sensors are particularly significant in this measurement.
